We have compared in 25 patients ease of placement of the conventional and intubating laryngeal masks while the patient's head and neck were stabilized by a manual in-line method, in a randomized, crossover study. After induction of anaesthesia and neuromuscular block, the masks were placed in turn. Adequacy of ventilation and ease of placement (using a 10-cm visual analogue scale (VAS)) were as...

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The larynge...

BACKGROUND The intubating laryngeal mask has been used for the emergency management of the airway in patients placed in the lateral decubitus position. We have conducted this prospective study to compare the feasibility of placement of an intubating laryngeal mask and blind tracheal intubation guided by the intubating laryngeal mask in patients placed in the right and the left lateral positions...

Laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. Insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). The present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...

hemodynamic changes are major hazards of general anesthesia and are probably generated by direct laryngoscopy and endotracheal intubation. we designed this prospective randomised study to assess the cardiovascular changes after either laryngeal mask airway (lma), face mask (fm) or endotracheal tube (ett) insertion in the airway management of adult patients anesthetised with nitrous oxide and ha...

THE LMA CTrachTM system (The Laryngeal Mask Company, Singapore) was developed from the LMA FastrachTM system (The Laryngeal Mask Company) and consists of an LMA CTrachTM airway with fiberoptic channels and a detachable liquid crystal display viewer cum light source. The LMA CTrachTM enables ventilation, glottis visualization, and tracheal intubation via a laryngeal mask conduit. In this report,...

The laryngeal mask airway has become one of the major tools of modern anesthesia airway management. Despite the fact that no time limit has been recommended regarding its safe use in spontaneously breathing children, or adults, there is still reluctance to use the laryngeal mask airway in operations of long duration. We report the case of an uneventful 5-hour long laryngeal mask anesthesia in a...
